Manchester United boss Sir Alex Ferguson has hinted at problems with Carlos Tevez's advisors when he had him at Old Trafford.

Ferguson had his own problems with Tevez and his advisers before the player finally left Old Trafford and joined Manchester City in July 2009. So he knows what he has had to handle.

Fergie admitted: "Management today is a complex situation in terms of the type of player we have to deal with.

"A lot of players are dominated by their agent. You get agents who buy their groceries, do their travel, polish their boots!

"It is different from when I started. It is more difficult to deal with."
